Not sure about the earlier 'Vette bias tires, but I know we've driven a *LOT* of miles on Polyglass tires in our various Chevelles/Novas/Camaros, and they've been fine for me...granted, we're not talking late model ZO6 type handling, but the older suspensions weren't designed for radials anyway, so any gains from tire upgrades will be limited without performance suspension upgrades...and I couldn't get our Eagle GTs to 60' with our Polyglass tires anyway!
BTW, good to see ya around here John Z...
